Patent number: 8509776Abstract: A method, information processing system, and wireless communication system, initiate a handover scanning procedure with a wireless device. The method includes monitoring a first signal strength measurement (606) transmitted by a wireless device (108). A second signal strength measurement associated with the wireless device (108) that is measured locally is monitored (606). The method also includes determining, in response to monitoring the first signal strength and the second signal strength measurement, if a scan event trigger has been detected (608). A scan initiation message is transmitted (614) to the wireless device (108) in response to a scan event trigger being detected. The scan initiation message signals the wireless device (108) to perform handover scanning procedures.Type: GrantFiled: December 19, 2007Date of Patent: August 13, 2013Assignee: Motorola Mobility LLCInventors: Ravi M. Adatrao, Tommy Chang, Pramod Karnam, Apurv Mathur, Robert S. Nikides

Patent number: 8509772Abstract: A method and apparatus for that provides a re-entry procedure following a radio frequency outage in a wireless communication network is disclosed. The method includes providing (204) a entity identification for a base station (102-106) or a paging controller (108) to a mobile station (110) during initial entry of the mobile station to a wireless communication network. The method also includes storing (206) mobile station context information at an entity corresponding to the entity identification. After a radio frequency outage occurs after the initial entry of the mobile station into the network, a notification is sent (218) that indicates that the mobile station is re-entering the wireless communication network. Based on the notification that there has been a radio frequency outage, the mobile station context information is obtained (220) to assist the mobile station to re-enter the wireless communication network.Type: GrantFiled: July 12, 2012Date of Patent: August 13, 2013Assignee: Motorola Mobility LLCInventors: Mark J. Marsan, Ravi M. Adatrao, Pramod Karnam

Patent number: 8462729Abstract: One determines (101, 102) that a given wireless mobile two-way communications platform is updating its network location (using, for example, an 802.16(e)-compatible protocol) at a time when there is no downlink traffic to provide to the platform and at a time when the platform should conduct at least one of an authenticator relocation process and an Internet Protocol address renewal process. In response to such determinations, one then automatically provides (103) to the platform, as part of updating the network location for the platform, an indication (such as, for example, a downlink traffic pending (DTP) flag) that the platform has pending downlink traffic notwithstanding that there is, in fact, no downlink traffic to provide to the wireless mobile two-way communications platform. Subsequent to this, one can then automatically cause (104) the platform to effect at least one of the authenticator relocation process and the Internet Protocol address renewal process.Type: GrantFiled: December 31, 2008Date of Patent: June 11, 2013Assignee: Motorola Mobility LLCInventors: Pramod Karnam, Alex P.

Patent number: 8051353Abstract: A method is described for providing Hybrid Automatic Repeat Request (HARQ) transmission feedback to a higher layer protocol in a communication system. The method includes a step of detecting HARQ retransmissions in a first layer protocol. This can be used to determine a HARQ failure or an HARQ ACK after a delay of some retransmissions. A next step includes providing feedback information about the detecting step from the first layer protocol to a higher layer protocol. A next step includes instituting corrections at the higher layer protocol, in response to the information transferred from the first layer protocol. These corrections can include immediate retransmission of those bursts of a HARQ failure, or correcting timers to match the delay of eventually ACK'ed data.Type: GrantFiled: October 23, 2007Date of Patent: November 1, 2011Assignee: Motorola Mobility, Inc.Inventors: David R.

Patent number: 7342939Abstract: Various embodiments are described to address the need for an apparatus and method for providing uplink communication resources that reduce some of the existing delays in acquiring these resources. In general, they may involve a RAN (121) transmitting data to a remote unit (101) via a downlink communication resource. After transmitting the data and with no additional data ready for transmission, the RAN begins transmitting assignment messages to the remote unit for an uplink resource. However, these assignment messages are not transmitted in response to uplink resource requests from the remote unit. In addition to or alternatively, the RAN detects a regular pattern in uplink activity of the remote unit and then begins predicting, based on the pattern, when the remote unit will next need an uplink resource. When the remote unit is predicted to need an uplink resource, the RAN transmits an assignment message to the remote unit.Type: GrantFiled: December 17, 2004Date of Patent: March 11, 2008Assignee: Motorola, Inc.Inventors: Alok H.

Publication number: 20070129088Abstract: A method and a system for performing cell reselection during an information transfer between a mobile device and one or more base stations in a network are provided. The mobile device extracts the RF environment information and sends it to the base station. The base station determines the time at which the cell reselection needs to be performed. The cell reselection is performed, based on the RF environment information, the amount of information that remains to be transferred between the mobile device and the base station, and a pre-defined condition of the information transfer.Type: ApplicationFiled: December 5, 2005Publication date: June 7, 2007Inventors: Zhou Gao, Pramod Karnam, Patrick Marcell

Publication number: 20040085923Abstract: A method and apparatus for transferring communication within a communications system. A target cell is identified to which to transfer communication from the RU. A cell reselection request to the target cell is then initiated for requesting transfer of RU communication from the source cell to the target cell. The RU disconnects from the serving cell and any data from the SGSN to the RU is buffered by the serving PCU. The serving PCU and the target PCU detect the occurrence of the cell change prior to the SGSN detecting the cell change. As a result, the buffered data is transferred from the serving PCU to the target PCU prior to the network detecting the cell change and prior to a FLUSH-LL message being transmitted from the SGSN to the serving PCU.Type: ApplicationFiled: November 1, 2002Publication date: May 6, 2004Applicant: Motorola, Inc.Inventors: Kamran Arif Qazi, Pramod Karnam, Trang Nguyen
